A secure drain connection is essential for safe filter operation and easy servicing. The Swimables Drain Plug Hand Nut for Pentair FNS Plus Filters (SW-26-030) is a direct-fit replacement designed to restore a tight, dependable seal at the drain port of Pentair FNS Plus DE filters.

This hand nut secures the drain plug assembly in place during normal operation and allows for tool-free removal when draining the filter for maintenance or winterization. Over time, original hand nuts can crack, strip, or lose their ability to hold tension—leading to leaks, pressure loss, or difficult service access. Replacing the hand nut ensures proper sealing and reliable performance without over-tightening.

Manufactured to OEM-equivalent specifications, the Swimables SW-26-030 offers precise fit and durable construction at a cost-effective alternative to factory-branded parts.

Secure, Tool-Free Drain Plug Retention

The hand nut is designed for easy grip and proper torque by hand, allowing quick removal and reinstallation during routine service. A properly fitting hand nut helps maintain consistent pressure inside the filter tank while preventing slow leaks at the drain port.

Reliable sealing protects surrounding equipment and keeps the filtration system operating efficiently.

Designed for Pentair FNS Plus DE Filters

The SW-26-030 is engineered specifically for Pentair FNS Plus DE filter systems, matching the original thread profile and sealing geometry. Using the correct hand nut prevents cross-threading, uneven sealing, and damage to the drain plug or filter housing.

Correct-fit components are critical for maintaining filter integrity and serviceability.

Durable Construction for Pool Equipment Environments

Drain plug components are exposed to pressure, moisture, and pool chemicals. This replacement hand nut is made from durable, chemical-resistant materials designed to withstand repeated service cycles and outdoor conditions without cracking or deforming.

Its robust design supports long-term reliability with normal maintenance.

Even small drain components play a major role in filter safety and performance.
